Application filed June 13, 1917. Serial No. 174,430.

To all 107mm it may concern Be it known that I, EDWARD WV. JENKINS, a citizen of the United States, and resident of Norristown, county of Montgomery, and State of Pennsylvania, have invented an Improvement in Machines for Tying Bundles, &c., of which the following is a specification.

The object of my invention is to provide a machine for conveniently, quickly and effectively tying or binding bundles, packages, boxes,etc., and especially adapted to commercial requirements of store and factory purposes where there are large numbers of bundles to be tied. My object is further to provide a suitable construction of bundle tying apparatus which shall be inexpensive and durable, and moreover, adapted to enable the bundle to be bound in a very tightand strong manner.

With these and other objects in view, the nature of which will be morefully understood irom the description hereinafter, the invention consists in the novel. construction of bundle tying apparatus as hereinafter more fully described and defined in the claims.

Referring to the drawings :-Figure 1 is a front elevation of a bundle tying machine embodying my improvements; Fig. 2 is a side elevation of the same; Fig. 3 is a plan view of the same; Fig. 1 is an inverted view of the knot-tying mechanism removed from the machine; and Fig. 5 is a sectional view on line m-m of Fig. 2 showing a detail.

2 is a table upon which'the bundle to be bound is placed, and is provided with downwardly extending feet or projecting portions 3 to support it above a counter or other suitable support 1 and to provide between it and the table 2 a space or chamber 5 in which the knot-tying mechanism 6 is lo-' cated. Extending upwardly from the table 2 is a bracket 7 carrying at its upper end a horizontal stud 8 upon which is journaled a binder arm '9 with. provision for oscillation, and a fly wheel 10 having a crank arm 11 by which it may be rotated.

The binder arm 9 is provided with a radial portion from the outer endof which e'xtends ahorizontal overhanging portion 12 terminating at its extreme end in a cord guide 13 in a vertical plane through the knot-tier 6, said cord guide being of tubular form andprogectlng obliquely to a radial' line through the axis of the binder arm.

degrees.

(Fig. 2), so that when the binder arm is moved downwardly, the. cord guide 13 will deliver the cord into the knot-tier 6, the

P t nted M i 1 1920- cord passing through the slot 2 in the table 2. 14; is a Y.-shaped arm which is pivoted at 1 5 toIthe. bracket 7 and one of the exten SlOIlS of this arm is connected by a link 16 with a crankpin 17 on the fly wheel 10 so that when the fly wheel is rotated, thearm The other extension of the arm 1 1 is connected by a link 18 with the binder arm 9 at a short distance from its axis of oscillation. When the arm 14: oscillates,,as' above stated, it is manifest that through the link 18 the binder arm 9 is also oscillated about the stud 8 from a vertical position,as shown in Figs. 1' and 2, through approximately 180 degrees to deliver the cord 19 intothe knot-tying mechanism 6. In swinging about its axis, the radial portion of the binder arm passes through the slot 2 in the table 2, and the horizontal or overhanging portion 12 of the binder arm' passes under the table so that its tubular guide end'13 may be'brought into close operative position with the knot-tying mechanism 6.- It will be observed therefore that the distance from the axis of the stud'8' to the edge 2 of the table'must be less than the radial clearance of the part 12 of the binder arm from its axis of oscillation;

20 is a cord controlling arm for the cord and is loosely pivoted upon the stud 8 and provided at its outer end with a cord guide aperture 21 through which the cord passes toa guide 22 on the binder arm 9. This cordcontrolling arm 20 is provided with a lug 23' which is free to oscillate between the stops'24: and 25 on the end of the bracket 7 (Figs. 1 and 2), so that the said arm 20 is free to oscillate through approximately 90 26 is a tension clamp under which the cord passes and by which tension is put upon the cord to prevent too much freedom in the passage of the cord to the binder arm. This tension clamp consists of an arm at one end resting'against the cord controlling arm 20, and having at the other end a clamping surface between which and the arm 20 the cord passes, the middle portion of the tension clamp having an aperture 27 j usted by means of a thumb screw 29 carried by the cord controlling arm 20. The construction of the cord controlling arm 20 and the binder arm 9 is such that when the binder arm returns to the position indicated in Fig. 2, 'it returns the cord controlling arm 20 also to the position indicated in Fig. 2. When the binder arm is oscillated in the forward position as in putting the cord around the bundle and leading .it into the knot-tying device 6, the cord pulls upon the cord controlling arm 20 and moves it forward with the binder arm until the lug 23 reaches the stop 25 when it is arrested, while the binder arm moves onto the knot-tying devices. This cord controlling arm 20 is therefore moved into the position shown in Fig. 2 by the binder arm 9 contacting with it on its return movement, and is also moved in the other direction by the pull of the cord .when the binder arm has been moved forward on its way to the knot-tier 6 and thereafter the cord necessary for wrapping the bundle and tying the knot is delivered under tension. By stopping the arm 20 and pulling the cord through the tension device by the binderarm, the cord necessary for wrapping about small as well as large bundles is assured. Ordinarily, the cord comes from any suitable source of spool arranged over-- head, passing downward through the aperguide 13 at the free end of the binder arm,

and thence downwardly through the slot 2 to the cord clamp 31 .(Fig. 4) of the knottying device. 7

While the knot-tying device may be con structed in any suitable manner, that shown is a type which has been developed by me and is excellently adapted forthe'purpose of my improved package binding machine. Thisknot-tying device consists essentially of a frame 32 which ispivoted upon a fixed stud 33 and adapted to be oscillated by a link 34, a lever 35, a second link 36 anda crank 37, the latter being secured to a vertical shaft 38 having a beveled pinion 39 at its upper end which is adapted to be engagedby a segmental rack 40 carried by and rotating with the fly wheel 10. -This shaft 38 is ournaled in a housing 41 extending downwardly from the fixed stud 3 upon which the fly wheel and the binder arm are journaled. The pinion 39 has a hub portion having a flattened surface 42 which, when in contact with the circular guide surface 43 of the hub of the fly wheel 10,holds the pinion and its shaft against rotation and with the crank arm 9 in the position indicated in Fig. 4. VVl 1en the rack 40 is about to engage the pinion 39, the termination of the flat guiding surface 43 through the length of the arc of the rack 40, will permit knot tying device, 44 is a looper bill which is ournaled in the frame 32 and provided at its outer end witha pinion 45 which engages a rack 46 secured to the under side of the table 2. \Vhen the frame 32 is oscillated, the looper bill 44 is caused to rotate, first in one direction and then in the other, and at the same time to travel in an are about the stud 33 located to one side of the cord holder 31. The cord holder 31 may be of any Stilt.

able type, and is generally composed of a stationary member and a movable member by which latter the cord ends are frictionally held in the stationary member, and I do not restrict myself in any way to this particular detail of'the knot-tying device. The general construction of the knot-tier herein illustrated is more fully described and-illustrated in Letters Patent No. 1,239,793 and granted to me on September 11, 1917, and to which reference is made for a more full description of a suitable knot-tier adapted to my particular in'iprovements of this application.

In general, the operation of the apparatus may be described as follows :-The parts being in the position indicated in Figs. 1 and and the bundle or package to be bound being placedupon the table as indicated in dotted lines at A (Fig. 1), the fly wheel 10 is rotated by the handle 11, and this causes the binder arm 9 to be swung from its position shown to a position below the bundle and under the table to carry the cord into the kn ot-tier. While this operation is being performed, the cord controlling arm 20 is ioved forward with the binder arm until the stop 25 is reached before the completion of the downward movement of the binder arm, and thereafter the tension device of the arm 20 supplies the cord under the requisite tension as the binder arm continues its advance to give cord to wrap the proximately one-quarter of a revolution of.

the fly-wheel, the knot-tier mechanism is put into operation for tying the knot, but during the remaining portions of the revolution it is quiescent or inactive. At the completion of the operation oi the knot-tying device, the

cord is'severed by a cutter 47, thereby liberand when the binder arm advances and wraps the cord about the bundle, this arm 20 will be drawn forward until arrested by the sto it traversin ap )roXimatel 90 l g ll .5 v

degrees to give cord freely to insure the initial wrapping of the bundle. The final wrapping operation and tying of the knot is performed with the cord under tension.

lVhile I have shown a crank handle 11 for rotating the fly wheel 10 and thereby imparting motion to the various parts, it will be readily understood that any suitable power maybe applied to rotate the fly wheel it desired, and it will also be seen that the mechanism may be operated without requiring that the fly wheel shall completely rotate, as substantially the same results would be accomplished by making it oscillate through 180 degrees and which might be accomplished in any suitable manner. I

therefore do not restrict myself to the particular means of applying the power for operating the machine, as this would be varied to suit the requirements or conditions available where the machines would be employed.

While I have in the present instance shown and described the preferred embodiment of my invention and which has been found in practice to give satisfactory and reliable results, it is to be understood that I do not restrict myself to the details, as the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention.
